o all whom if, may concern:

lle it known that I WILLIAM Il. WALTER, a citizen oi the United States,residing at Chicago, in the county oi' (look and State of Illinois, haveinvented new and useful Improvements in Liquid-Dispensing Mechanism, ofwhich the following is a specification.

This invention is a coin operated machine for dispensing liquids, andcomprises valve controlled means to measure and dispense the liquid. Itis intended to be used in stores, cafs, and other public places for thepurpose of dispensing liquids, and includes as an especial feature meansfor cooling the liquids so dispensed. It will serve to put withinconvenient reach oi all persons a cheap and cool drink, by a novelmechanical means to be hereinafter described.

In the accompanying drawings, Figure l is a vertical section of thedevice. Fig. 2 is a detail in section showing the valve passages. Fig. 3is a detail in horizontal section on the line 3 -3 of Fig. 1.

Referring specifically to the drawings, 10 indicates an outercylindrical casing which contains the coin operated valve mechanism andalso the ice chamber through a coil in which the liquid is discharged.The valve operating mechanism and parts of the apparatus are containedin an upper chamber 11. The lower or ice chamber l2 is provided with aninsulation 12* to retain the cold and serves as a rcirigerating chamberfor cooling the liquid sold.

13 is a. reservoir, preferably a large glass bottle, which is invertedso that it discharges through the mouth 13.

This is mounted in an opening on top of the casing 10' with the neck oithe bottle extending through the opening and the shoulder oithe bottleresting on top of the casing. The mouth of the bottle projects into andis sealed in a trap vessel 14 in the upper chamber, and leading from thebottom oi this vessel is a tube 14* which is provided with a.controlling valve 18.

At .i6 are indicated two closed msuring cups, which determine thequantity of liquid supplied at cach operation, and these cups arerespectively filled and discharged at each operation of the device, onecup being filled while the other is being emptied. Air tubes 15 connectthe top of the cups with the vessel 14, so as to provide an air vent toallow the cups to fill and also to return any overfiow into the trapvessel 14. 'lhcse cups are connected by pipes 17 to the controllingvalve 18, which is a four-way valve, as shown in Fig. 2, and isconsequently operated by a quarter turn. The main discharge pipe i9leads down from the valve into the refrigcrating chamber 12 at thebottom of which it is provided with a coil 19* which terminates in adischarge nozzle 19b which extends through the wall of the casing'inposition to fill a glass on a bracket 19.

19d is a drainage tube having one branch extending tothe bracket andanother brauch forming an overflow from the ice chamber with a halfcircle air trap 19 at the top. Leading into the main discharge. pipe 19near the upper end thereof is an air vent pipe 32, forA the purpose ofrelieving the air or air pressure from the coil and assure a perfectdelivery of the fluid. This air vent joins the pipe 9 on substantially alevel with the nozzle 19".

The valve 18 may be operated `by any desirable or suitable coinmechanism. I have indicated such a mechanism, as a whole, at X. y

In the operation oi the device thecoin is deposited in a slot providedfor the purpose, and by means of the coin mechanism referred to thevalve is given a quarter turn. The coiland delivery pipe are firstprimed by filling the same with the liquid tothe level of the -dischargenozzle. When the vmechanism is actuated the liquid will flow from thebottle or reservoir through the pipe 14 and through one of the ports ofthe valve into one of the cups 11,6, filling said cup, and at the sametime the other cup 16 will discharge through its outlet` pipe and theother port of the valve, Vinto the discharge pipe 19, as cloarlyshow'nin Fig. 2, causing a corresponding discharge from the delivery nozzle.At the next operation the respective cups are emptied and filled in asimilar manner. There is thus always a charge or quantity of liquid tobe delivered inthe cooling coil, where it remains until the device visoperated, and during which period it is effectively cooled,

I claim: i

In a liquid dispensing mechanism, in combination, a cn'sing having anupper: chamber and a lower refrigernting chamber, a liquid-reservoircomprising an inverted hottie the neck ot which extends through anopening in the top o! the casing, a trap vessel in the upper chamber,into which the mouth of the bottle extends, a four-way valve and itscasing located in said upper chamber under the trap vessel, a pair ofmeasuring cups located in the upper chamber and having pipe connectionswith the vnlvsfcasing and vent pipe connections trom the top thereof tothe trap vessel, a pipe connecting the trap vessel and the valve casing,and a delivery pipe extending from the valve casing down through theretrigernting chamber and having a coil in the bottom of said chamberand a diselm" nozzle above the coil, whereby a quantity ot liquid isretained in the coil at alliimes, the valve being constructed to iilione measuring cup and empty the other at each operation.

In testimony whereof I have signed my name to this specication in thepresence ot two subscribing witnesses.

WILLIAM II. WALTER.
